Former Rangers defender Kevin Muscat is reportedly in the running to join Ange Postecoglou's Celtic backroom team.
The former Australia manager remains the favourite to succeed Neil Lennon at Parkhead despite potential issues over a lack of UEFA Pro Licence.
However, Postecoglou's position as Celtic frontrunner has split opinion with the fans and coaching team could also be set to divide the supporters.
The Scotsman report that tough-tackling former Ibrox defender Muscat is 'in the frame' to join his countryman at Celtic Park.
The tough-tackling defender lifted a Treble during his time in Glasgow under Alex McLeish and could cross the divide to return to management in the Scottish Premiership.
The former Australia cap has been out of work since leaving Belgian side St Truiden after six years in charge of Melbourne Victory.
During his time in Europe, Muscat faced a similar issue that could be posed to Postecoglou over the A-Licence.
St Truiden were forced to name him as technical director and Muscat could not take training or be involved in games after his A-Licence, which was completed within the Asian Conference, wasn't deemed sufficient.
